Testimonials
Rave reviews from companies like yours.
Outstanding
This is my second venture and second time with BayBiz and I wouldn’t have come back if their service wasn’t outstanding. I use them for their suite of services and David is always available if needed but Kerry and Mary do such a great job, I almost never need to bother the boss. Highly recommended if you want to spend more time doing business and less time on back office activities.

Shay Hancock
Meaningful & timely
By partnering with Bay Business Group, they have streamlined my accounting operating procedure, accounting operation, and given me meaningful & timely monthly reporting. This in return gives me quicker problems resolutions as they arrive. Bay Business Group has been proactively suggesting improvement to accounting reporting, interpretation of accounting reports and improvement to the accounting system. Giving me a way to measure the performance of my business and more time to work and tweet improvement to my business operation and product lines.
